ELECTRICAL PERMANENT-WAVING DEVICE. I

Application filed Fe ruar 25, 1928. Serial No. 25 ,3 8.

This invention relates generally to hair curlers for. human hair, andhasmore particular referenceto a novel hair curler capable of producingpermanent'waves.

The invention has for an object the provision of a device of the classmentioned, which is of simple durable construction, dc sirable and:efficient inaction, and which can be manufactured and sold at areasonaable cost. v

The heater elements of the device are of oval shape which makes thewaves tight on the small ends and soft on the large sides, thuseliminating the customary setting step after the heat treatment, whichof course saves time. Heating windings. are arranged within the heaterelements so that the hair is heated from the inside when applied:

to theheating elements, giving it an opportunity to allow steam to workthrough every single hair. These heating windings 6X- tend the fulllength of the heating elements so that the same amount of heat exists atthe center and ends of the heater elements. The size of the oval shapeof the heater ele-' ments determine the size of the waves produced.These heater elements may be provided with means for varying theoperative size of these oval shapes. I e

For further comprehension of fiJhG'lliVGlltion, and of, the objects andadvantages thereof, reference will be hadto the following descriptionand accompanying drawings, and to the appended claims 1n WhlCl] thevarious novelwfeatures of the invention are more particularly set.forth. Referring to the accompanying drawings,

forming a material part of this disclosure Fig. 1 is a sideielevational.view of a heater element constructed according to this invention.

Fig. 2 is a perspective view of a device for holdingthe heater elements.

Fig.3 is a View similar to Fig. 1, but'a front portion thereof is brokenaway, disclosing .the interior construction.

Fig. 4 is a horizontal sectional view, taken on the line 4-4: of.Fig. 1. I V

Fig. 5 is a similar view, but disclosing a modified form thereof.

Fig. 6 is a sectional view of a modified.

form of heater element, takenv as though looking in the oppositedirection of the arrows 44 of-Fig. 1. I

Fig. 7 is a fragmentary sectional View,

taken on theline 77 of Fig. 6.

The reference numeral lOindicates generally a tubular body member ofoval cross section, having a heating winding 11 ex tending from one endthereof completely to the other end, a steady head 12is engaged in oneend'of the tubular body member, and

a plug connection 13 is securedon the other end andconnected with thewinding 11, and this structure constitutes the heating ele-- ment of thedevice. The head 12 is formed .with a cut 14 to accommodate hair whichmay be tied in place by a string. The plug 13 has along body 15 ofinsulation material, which can be used as ahandle whe the heater elementis hot.

These heater elements are used in conjunction wifth a device forsupporting them, and consisting of a plurality of complemcntary plugs 17connected with cables 18 supported on bracket 19 provided with a maincable 20 for connection with some source of electrical power. v

Fig. 5 illustrates a tubular member 10 and a winding 11 of greater sizethan the Q member 10 and winding 11. The size of the tubular memberdetermines the size of the waves produced thereby.

Figs. 6 and? illustrate a heating element which may be varied in size,that is, with respect-to the size of the oval shaped member. Thisheating element consists of a'central heating winding 21 with an ovalshaped tubular member 22. A plurality of curved of the member 22, sothata large size oval shaped heating element is produced. A pluralityof. screws 24 threadedly engage the body 15 of the plug, and abutagainst the outer curved members clamping all the tubular membersin'place. The frontsof these tubular members'are provided with cuts 14so that hair may be securely 'h'eld. Should i a smaller size heatingelement be needed, the screws 24 are loosened, and the outer curvedmembers removed, thenthe screws are reset.

While I have shown and described a preferred embodiment'of my invention,it is to be understood that I do not limit myself to the right isreserved to all changes and modifications coming within the scope of theinvention as defined in the appended claims.

Having thus described my invention, what;

members 23 are engaged on top and bottom i -the precise constructionherein disclosed and I claim as new and desire to secure by Unit edStates Letters Patent is l. A heating curler element for the purposedescribed, comprising a tubular body member of oval cross section,heating means therein, a plurality of curved members ongaged on the topand bottom of said tubular body member, and means for removably holdingthe curved members in place.

2. A heating curler element for the purpose described,.comprising atubular body member of oval cross sect on, heating means therein, aplurality of curved members ongaged on the top and bottom of saidtubular body member, and means for removably holding the curved membersin place, com prising screws engaged in the heating curler and abuttingagainst the outer curved member clamping all the curved members 2 inplace.

3. A heating curler element for the purpose described, comprising atubular body member of oval cross section, heating means therein, aplurality of curved members engaged onthe top and bottom of saidtubularbody member arranged for removably maintaining their places.

4. A heater element for a device of the class described, comprising anoval body member with opposite sharp curved sideson the major axis ofthe oval shape, and with substantially fiat sides on the minor axis ofthe oval shape for forming a tight Wave on the portion of a strand ofhair applied on the sharp sides and a soft loose Wave on the portion ofa strand of hair applied on the substantially flat sides. y

In testimony whereof I have aflixed my signature.
